Welcome to Physics and Astronomy


Undergraduate

For undergraduate students, we offer majors in PhysicsAstronomyBiophysics, and a joint Physics/Computer Science program. We also offer minors in Physics and Astronomy.

Graduate

For graduate students, we offer a Ph.D. in Physics. If you are a prospective graduate student, please take a look at the Ph.D. section for all the information on application to our Ph.D. program.

Research

Physics and Astronomy are both going through revolutionary times mirrored by the research programs in the department, which range from theory of High Energy PhysicsCondensed Matter Physics, to Cosmology. Large Scale Computation is an important field with several state-of-the-art facilities available to students and faculty. Emerging areas of research in our department include the rapidly developing fields of Quantum Information Science and Physical Biology. Biological Physics is where the quantitative skills of physicists address important problems coming from biological systems.

Your Major & Minor

The Department of Physics & Astronomy offers majors and minors in five different subject areas. It also offers several different levels of introductory courses for students with majors in other departments.

A Trojan Welcome to James Bullock

Astrophysicist James Bullock has been named dean of the USC Dornsife College of Letters, Arts and Sciences, effective July 1, 2025. Bullock will be the 23rd dean to lead USC Dornsife since its founding in 1880. He succeeds Amber Miller (Cosmology), and takes the reins from interim Dean Moh El-Naggar. (Physics and Astronomy).

Welcome Dean Bullock to Dornsife and Physics and Astronomy!

If we can improve our predictions concerning changes in the number of sunspots and the activity of the solar cycle, then we may be able to improve our knowledge of space weather and determine what is likely to cause major problems on Earth and what isn’t.
